SPECIFICATION forming part of Letters Patent No. 761,294, dated May 31,1904. Application filed my 28,1902. serieiNo. 117,325. (Numan.) l

To @ZZ whom it may concern:

Be it known that LLoN GRIvEAUD,a citizen of the French Republic, and a resident of Paris, France, have invented certain new and useful Improvements in Posts for Supporting Telegraph-Wires, Cables, and the Like, of

-which the following is a'specification.

This invention -relates to metal line-postsand statiOD'rDosts which can be employed with advantage as supports for wires or cables used e in Vtelegraphy, telephony, transmissions of power, and tramways on the trolley system,

'as well as for all kinds of lighting and signalmuch alike in both cases and the former only differing generally from theY latter as regards the way in which they are fixed, the line-postsy being insulated and lixed with the lower part in the ground, while the station-posts are fixed by horizontal rodsvor brackets to constructions alreading existing-a wall, a roof, or a post. l y V The external form of my post or of the truncal divisions of whichitconsists has induced me to give it the distinctive name of 'ing it may be of any kind; The configurations forming the sides of the hollow prism are made of iron or steel or any other hardl substance produced by metal-works. The fixing blocks or frames employedfor insuring the xtures of the posts are made of cast-iron, iron, or wood, &c.

In order to completethe explanation, I have indicated in the drawings accompanying this application for a patent some arrangements in conformity with the principle enunciated and which may be more generally in use.

Figure 1 is a view in elevation giving a gen.

eral representation of a prism-post composed of three truncal divisions A A A2. It is furnished with a base S, annular moldings D, and

.an apex P, which may be made of cast-iron and of any shape. Advantage is taken of the base S to disguise a strengthening part running nearly to the upper part of the base in the dangerousv part of the post. This part consists of a double T-piece E, arranged as shown in the horizontal sections illustrated in Figs. 5 and 10. The lower end of' this piece E may be provided with two angle-irons riveted or bolted to the part which most directly bears the weight of the post. e

Figs. 2 and 3 illustrate the former a piece in elevation and the latter a horizontal section of a very simple and very useful contrivance.

The pieces A, which form the sides of a hollowv increases its strength and at the same time e closes the space left between the inturned ends of piece'A. The interior frames C are dou- 'Ihey may, however, be entirely omitted if the feet of the T-piece Ebe furnished with a projection'against which the flanges of the pieces A can rest. .This continuous projection could be replaced by screw-pegs? placed at certain distances'apart.

Fig. 6 is a horizontal section in which the pieces A hold tightly between their flanges doubly-grooved pieces E. The pieces E may becontinuous or simple short pegs. In this figure the metal frames are replaced by blocks of wood.

Figs. 7 and 8 represent a post in which the pieces A are semicircular hollow pieces rolled, bent, or embossed. If there be any space between these pieces, it may be'stopped through- Out or over a part of the height of the support by a configuration of any kind, such'as E2, which will at the same time increase the strength and fill up the space. The pieces A may be screwed onto the frame C or be tightened by means of' a hoop F in one piece put on hot or in two pieces bolted together.

Figs. 9 and 10 represent a piece in elevation and a section of' a post in which the parts A directly lock a double T-piece E. The parts may be kept together by the bolts B without the employment of' frames or interior pieces.

In Fig. 11 the double T-piece which forms a part of the preceding construction is rel placed by two single T-pieces E3, held tightly by the arms or flanges of the pieces A and simply connected at certain points by bars H, iXed to the bodies of the T-pieces.

General fmcmgcmcm. The description given above and the drawings which accompany this application can only serve for more clearly fixing the principle explained. It will be seen that a transverse section may bea polygon of' any kind, even a circumference, and consists of elements of dilferent forms rolled, bent, or embossed. I thus reserve not only the right of making use of' configurations known in commerce, but likewise that of' rolling'special configurations which may appear to me to be more suitable, either owing to their particular form or their more economical transverse dimensions. for example, have rolled U-shaped forms of' slight thickness or with very wide flanges in order to place them together without any intervals, the edges of the arms being planed or not planed. With the purpose of' filling up the spaces between the angular pieces orv of increasing the strength ofthe support I can employ metal or wooden rods or other I can,

configurations or again lill up entirely the whole hollow interior of a truncal division with some inert or resistant material, suoli as cemen t mortar. The interior frames, when these are necessary, may be made of' wood, east-iron, iron, &c. ln order to keep the angular pieces at proper distances apart, cast-iron bars or pieces of' iron rolled in double T shape, in U shape, sheet-iron bent or embossed, tube ends, Sac.,v may be used if the internal hollow space is in the form of a regular polygon. The joints of the different truncal divisions may likewise be varied according to circumstances and differ from the arrangements described, and shown in the drawings.

It will be understood thata fixed joint may be effected by simply riveting together the parts of' the truncal divisions which lap one over the other to the extent necessary.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A post of' the character described comprising a plurality ofl sections telescoping within each other, each of the sections comprising separable members spaced apart, means for spacing said members, said means closing` the space between the members, means for securing the members and said spacing means si.- multaneously together.

1n testimony whereof' l have hereunto set my hand in presence of' two witnesses.
